Abstract excerpt
The key to plant survival under NaCl salt stress is maintaining a low Na(+) level or Na(+)/K(+) ratio in the cells. A population of recombinant inbred lines (RILs, F(2:9)) derived from a cross between the salt-tolerant japonica rice variety Jiucaiqing and the salt-sensitive indica variety IR26, was used to determine Na(+) and K(+) concentrations in the roots and shoots under three different NaCl stress conditions...
